Explain forward and reverse biasing in short
Did you know?
WebReverse biased is the condition where a positive voltage is applied to the n-type and negative voltage is applied to the p-type material. Transistor biasing. The supply of suitable external dc voltage is called as biasing. Either forward or reverse biasing is done to the emitter and collector junctions of the transistor. WebOn applying a forward voltage to a PN junction device the depletion width decreases with the increase in supplied voltage. While, when reverse biasing is provided to a PN junction device then the width of the depletion region increases with supplied voltage. Due to forward applied voltage pn junction device acts as a good conductor after ...
